TURBINE WATER WHEEL.

SlEGII-ICATION "forming part of Letters Patent No. 321,660, dated July7,1885.

(No model.)

f0 all whom it may concern:

Beit. known that l, CHARLES R. SyLvEs'rnR, of Little Falls, in thecounty of Polk and in the State of Wisconsin, have invented certain newand useful Improvements in Turbine \Vater-i Vl'leels; and I do herebydeclare that. the following is a full, clear, and exactdescriptionthereof.

My invention relates to waterwvhccls or turbines, and will be fullydescribed herein after.

In the drawings, Figure 1 is a perspective view of the water-wheel. Fig.2 is a hori zontalsection of the same through gates. Fig. 3 is avertical section through center of wheel, the crown plate having beentaken off. Fig. 4 is a top plan view of the wheel proper.

A is the wheel'casing, having a flange, (1, with step Z), in which areformed mortises (not shown) forcrown-plate posts 0 c and holes forscrewbolts d rt, to connect said erowirplate D with wheelcasiug A.

d d are ribs for strengthening said casing, and into which to boltspider-legs d d.

c c" c are the water-guides or d irectriecs formed in the top ofsaidcasing A.

B is the wheel proper, which'has conical hub of, curved vanes b, andouter rim-plate, c, forming the wheel-buckets a (ii, the lower openingof which is shown by the dotted lines of Fig. 4 in If.

B is the whcelshaft.

G C are the water-gates, which pivot between posts cc on shafts d' d,passing through their flanged center. \Vhcn elosed,their front and rearedges respectively fit in recesses c and (2, formed in crowlrplate posts0 0. Their bent arms 1 i hinge in forked links 2' i. The central part ofthe crown-plate D has an elevated portion, f, in which is an annulargroove, 9, in which works the base of the an nular table 9. The innerrim of this base is overlapped and held horizontally in position by theannular piece 72, which is attached to the center of the crown-plate.Between the base of the table and an upper ring, which is secured toit,the inward end of links i i hinges on bolts j j j, which are usedalso in part for fixing to adjustingtable g bracket k of toothedsegmentl. To the forked end of links i is freely jointed end of bentarms '2' 2'! '11- of gates C O. The adjusting of said gates C O is doneby means of thehand-lever Z, aetnating pinimrbolt min usual manner. a isthe curved bracket supporting said pinionbolt an.

E is the tripod or upper spider, having center hole for shaft B.

E is the spider proper, and 0 0 the bolts to secure it to thewheel-casing A in ribs (2 (P.

I am aware that numerous attempts have been made to direct the water onthe buckets of water-wheels so asto secure the best action on saidbuckets; but I claim that by making the wheel with a scroll decliningfrom the center toward the rim, and with a decline also from the top ofthe buckets downward to the issue, I have devised a direct way to securethe fullest action and reaction of the water, the same being graduallyand equally closing on all sides of the buckets until itleaves them.Further, in the construction of my guidevanes-that is, in guiding thewater onto the buckets of the wheel by a set of independent guides,instead of using the wheel-gatesl obtain a sure and steady action, whichin the ordinary construction cannot well be secured, sin ce,as the gatesare being variously adjusted to suit the needs of the driven machinery,their larger or small opening must in some degree affect the course ofthe water.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, is-

1. An improved turbine water-wheel consisting of casing A, having flangea, step b, water-guides c c e, and ribs d (1 wheel proper B, havingconical hub a, curved vanes b, outer rim-plate, c and shaft B, of gatesO C, crown-plate D, having adjusting-table g, with ring 9", links iii,jointed freely with arms ii" of gates G O, curved bracket n, pinion-boltm, and pinion-operating toothed segment Z, spider E, having bolts 0 0,and tripod E, having central opening for shaft B, all the parts being incombination substantially as shown and described.

2. In a turbine water-wheel, the casing A, having water-guides c c c,flange a, step b, and ribs d d", substantially as shown and described,and for the purpose set forth.

3. In a turbine water-wheel, the combination of crown-plate D, havingposts 0 0, bolts d d, and elevated central portion, f, having groove g,gates O O, shafts d d, bent arms iz", forked links 2' 27, andadjustingtable g, substantially as and for the purpose set forth.

4. In a turbine water wheel, the combination, with the wheel-oasing A,having flange a, step b, and water-guides c c, of the wheel B, havingeone-shaped hub a, curved vanes Z), outer rim-plate, c and loweropenings, b, substantially as shown and described.

5. In a turbine Water-wheel, the combination, with casing A, havingflange a, step I),

and water-guides ccc', of crown-plate D, havlng posts a c 0, bolts d (2,and central elevated portion, f, having annular groove g, gates O O,

the shafts d? d, bent arms i i, forked links it,-

the adjusting-table g, and its gearing, substantially as shown anddescribed, and for the purpose set forth.

6. The combination of the casing A, the

the links 1 the arms 2', and the gates O, With the guides c, and thewheel B, having hub a, vanes I), and buckets a".

In testimony that I claim the foregoing I have hereunto set my hand,onthis 23d day of July, 1883, in the presence of two Witnesses.
